Hello, can I left the luggage at the hotel 4 days earlier before officially check-in as I planned to go a short trip to Paris beforehand.
Email the hotel directly.
I believe that fine
It's better to ask to the hotel.... I don't know
Definitely better to check with the hotel first.
Probably best that you call them to ask directly.
